Are Humans Computers?

Joosthere, a member of the LockerGnome community at large asked: "Looking at the definition of computers and then the definition of machines, humans appear to be a lot like "computers". Are we?"

This is one of those fundamental philosophical questions that have been on the minds of man since the first computer was conceived and created. Are brain functions on electric synapses and impulses that calculate and store information, much like a modern computer does. Does that mean that we could very well be defined as a computer, as well?
